The present invent-ion contemplates the provision or a pack frameforsupporting a load or package'A adaptedto he carried on the back of aperson, and the invention aims to provide a frame of this characterwhich `is simple*inconstructionand one which can be manufactured andsold at a nominal cost.

One of the chief characteristics of the present invention resdesinvaframe of the abovementioned-character constructed to be`comfortablysupported on the back of the `person, andicapableofaccommodating itself to packs orloads of different sizes.`

The natureand advantages of the-inventionjvvill be better understoodwhen the iollowing detaileddescription is read in connection with theaccompanying drawings, the invention residing in the construction,

con'ibination and arrangement of parts as claimed. ,s Int the drawingsforming lpart of this application like numerals of reference-indicatesimilar parts in the several views and Where- Figure 1 is a viewshowinghow the fram and its load is carried by theperson.

. Figure 5 is a top plan View.

Figure 6 is a sectional View on line (3*6 of lligurel.A l f The pack,frame forming the subject mat- 4ter ofthe'present invention is capableof being readily knocked downor taken apart and essentially embodiesspaced vertically disposed side members or bars 10 which may beconstructed from any suitable material, preferably wood, and thesemembers are spaced apart at points adjacent the upper and lower endsthereof by bowed transverse bars or members 11 and a similarintermediate bar or member 12. The .side members 10 are slotted. `orgrooved. to removably receive tongues 13 carried by the endsofthe bowedtransverse members as illustrated. The side members 10 are detachablyconnected andthe upper and lower transverse bowed members 11 arereinforced by metallic rods 14, which are arranged immediately behindmembers 11 Vand extend throughout the entire length of the'latter. Theextremities of each rod 111 are passed through the side members 10. Eachof these `ro'clsis provided with a head 15 atone end, while the oppositeend of each' rod is threaded and adapted .to accommodate athunib-nutil'for drawing. the side -members 10 together. These trans'-vversemembers are further braced. andslip-` ported by a verticallyldisposedmetallic rod 17, theupper. end of which .is bent atarightangle,to extend across the adjacent ,rodll and pass through the adjacenttransverse bowed member 11 as clearlyillustrated in Figures 4 and 5.This bent extremityof the rod 1-7 is threaded and provided with a suit.`able 'nut 18. The rod 17 is ,slightly inclined so that the intermediateportion'ofthe same willV contact the intermediate transverse bowedmember 12 ,to reinforce and brace .the

latter, while the lower end oftherod 17 is Y passedA through averticalopening formed in. the lower transversemember 11,and'is heldlinposition by a. suitable nut -19 threaded thereon. The frame element thus`far described `is covered by a sheet of canvas ,or other -rela tivelyflexible material at 20, Whichfsurronndsthe frame, and isofa'lengthtocomf pletely cover Yall of the transverse connect.-` ingmembers v11 and 12 respectively, although the side membersl() oftheframe project a slight. distance Vabove and below the v.leXibleVcovering 2O as illustrated. Thiscovering'is,

passed around vtheside;members'10 and provided with lopenings to receivetheprojecty-V ing extremities of lthe brace yrods14,while.` the .freeends or longitudinal edges of this covering are connected together by alace 21 so that` the covering can be partly A stretched and heldtight`about the frame. Upon inspection of Figuref it will be noted y that theportion of the'covering arrangedyin `advance of the frame isspaced-therefrom,

so that when the frame yis lsupported upon the 1f back of theperson,this portion of the canvvas willconltact the body, and servepas-V a .A

cushion for the entire structure, so that the frame can be carried withf both ease and comfort. p Y Y The pack or load indicated generally atQ2 is adapted to be supported on the rear of the frame, and heldassociated therewith by straps'as illustrated. Each of these strapsincludes a relatively long section 23 and a.

. size of the load 22. It will be noted however,

that these straps are crossed and extend diagonally across the rear ofthe frame in its entirety. Vihile these straps may be secured to theframeV in any suitable manner, each side member l0 is preferably slottedadjacent its opposed ends as at 26 and the adjacent end of each strap ispassed through one of these slots, looped around the side member l0, andhas its free end riveted or otherwise suitably secured to the strapproper, as at 2. i

vThe entire structure is Vsupported on 'the body of thev user byshoulder straps, arranged at the front and adjacentboth sides of theframeand each strapQS has one endl looped as at, 29V whichend carries asnap hook 30 adapted to 'be received by a ring 3l connected to theadjacentside member l0 adj acentl the lower end thereof in any suitablemanner. The looped extremity 29 of each strap also includes a buckle 32by means of which the length of the strap can be adjusted to varyitslength as thevoccasionmay require. The upper ends of each strap 28arel passed over the upper edge of the covering 2O and are securedy tothe uppermost brace rod 14 for the adjacentv transverse member 11.` Forthis purpose, the member 11 is provided' with spaced longitudinalslots33, and the adjacent ends of the straps 28 are passed through theseslots, `around the .adjacent brace rods 14, and have their free endsriveted or otherwise suitably secured to they straps proper as at 34.This construction is very clearly illustrated in Figure 6.

It will be noted that by removing the nuts:

16', l8and 19, the rods '14 and 17 may be Y detached, thusk permittingseparation of the bars-10, 1l and l2. The device may thereby be easilykand quickly knocked down and carried in a smallcompact bundlewhen no tin use. Y

Vhile it is believed that from the foregoing description the nature andadvantages of the invention will be readily understood, I desire to haveit knownl that I do not limit myself to what i-s herein illustrated anddescribed, and that such changes may be resorted to when desired as fallwithin the scope of what is claimed.

' lVhat I claim as new is:

1: A. pack frame comprising spaced sider members, bowed transverselyarranged members spacing the side members, reinforcing rods connectingthe side members and arranged behind said transverse members, each rodhaving its extremities passed through said side members, a sheet offlexible material constituting a cover for the frame, theupper and lowerends of the side members projecting beyond the cover, load carryingstraps secured to the side members and arranged at the rear of theframe, and shoulder straps carried by the frame and arranged at the jfront thereof. v

2. A pack frame comprising spaced side members, bowed transverselydisposed mem* bers spacing the` side members, reinforcing' rodsconnecting theA side memb-ers and arranged behind said transversemembers, each .of said rods having its extremities passed through theside members, a vertically disposedreinforcing rod terminally connected.ith said transverse members, a sheet of flexible material surroundingthe frame andronstraps carried by the side members and arranged incrossed relation at the rear of the frame, and shoulder strapscarriedbyv the frame and arranged at the .front thereof.

3. A pack framecomprising spacedside members,` bowed transverse membersspacing the side members adjacent the upper and lower ends thereof, anintermediate trans verse bowed member spacing the side members,reinforcing rods connecting the side members and arranged behind thefirstsnamed transverse members, each rod havingits ex-` Ymembers, bowedtransverse members spacing the side members, reinforcing rods connectingthe side members and arranged behind the transverse members, veach rodhaving its extremities passed through the` side members, f

the uppermost transverse member having spaced longitudinal slots in linewith the reinforeing rod thereof, a` sheet of flexible materialsurrounding the frame and constituting a cover therefor, loadsupportingstraps carried by theside members and arranged at the rear ofthe frame, and shoulder straps arranged at the front of the frame andhaving their lower extremities adjustably vconnected with the sidemembers, thev upper extremities of the shoulder straps being passedoverv the cover of the frame and throughV thefslots of the uppermosttransverse member and connected with the adjacent re- -inforcing rodthereof.
